1.2.1. Objectives of the Unit

Try these first

1. 1.

   What does a conditional instruction do?

   Hint

   Think about the 'if' statements in programming.

2. 2.

   Define the term 'unconditional jump'.

   Hint

   Recall how function calls work.

3. 3.

   What is the purpose of conditional instructions?

   • To execute sequentially
   • To alter execution flow based on conditions
   • To produce output

   Hint

   Think about 'if...then' statements.

4. 4.

   True or False: Unconditional jumps require a condition to be executed.

   • True
   • False

   Hint

   Think of function calls.

5. 5.

   Write a pseudocode that incorporates both a conditional and an unconditional jump. Explain each part of the code.

   Hint

   Think about the flow of alternatives.

6. 6.

   How would you modify an existing program to include a loop that checks a zero flag? Draft a solution.

   Hint

   Use a decrement operation to check where the zero flag comes into play.
